Description

A kind of hopping robot of symmetric form vertical jump in succession
Technical field
The present invention relates to mechanics, bionics, Robotics, hopping robot, environmental monitoring, particularly a kind of hopping robot of symmetric form vertical jump in succession.
Background technology
Mobile robot replaces static monitoring techniques node in environmental monitoring, has some superiority in the applications such as information acquisition, and multiple mobile robot's node can dynamic conditioning network's coverage area, network topology structure etc., reduces and covers leak and overlap.Common wheeled mobile robot node is along with the reduction of volume, and its ability adapting to rugged non-structure environment can degradation, and when obstacle is higher than himself height, wheeled mobile robot node is due to can not obstacle detouring and motion failures.Hopping robot can cross the obstacle higher than himself height several times, and higher position can be snapped into, strengthen wireless communication link quality, improve the stability of monitoring network, therefore hopping robot as monitoring node, can be applied to various environmental monitoring field.
When hopping robot is applied in non-structure environment, it needs to have continuous bounce locomitivity, constantly could regulate himself position.Continuous bounce motion needs hopping robot to have to land Self-resetting function, direction of take off regulatory function.Self-resetting comprises initiatively Self-resetting and passive Self-resetting, as the active self-resetting method used in Chinese patent ZL201210003779.3; As the wheeled hopping robot in Chinese patent 201110361030.1 and Chinese patent 201310087552.6 uses symmetrical structure, after robot lands, realize passive Self-resetting.Hopping robot in Chinese patent 201110361030.1 and Chinese patent 201310087552.6 uses compound wheel type mechanism to regulate direction of take off, and the spherical jumping robot in Chinese patent 200910108660.0 regulates direction of take off by the health rotated in spherical shell.
Hopping robot towards non-structure environment application needs to prevent environmental conditions from impacting it, comprise the collision on spring and ground, rainwater etc. cause damage to body Mechatronic Systems, wheeled hopping robot in Chinese patent 201110361030.1 and Chinese patent 201310087552.6 can not crashproof and waterproof, and although Chinese patent 200910108660.0 spherical jumping robot can accomplish waterproof, but this robot static instability, need constantly adjustment attitude could realize standing and take-off, for the perception of robot and control overflow too high, practicality is strong not, its spherical housing causes spring to land rear passive rolling, be difficult to accurately control anchor point, in addition its bouncing mechanism is asymmetric, the method that inner body and spherical shell collide take-off all can cause damage to spherical shell and body, be rolled to just in time upside down in situation, if there is barrier obstruction, the words that rolling moment is inadequate, can not roll and can not jump, there is motion failures.
Summary of the invention
Technical matters technical matters to be solved by this invention is, overcomes the deficiency of the repositioning method of existing hopping robot, Anticollision Measures, direction of take off adjustment etc., designs the hopping robot of the equal symmetric form of a kind of practical 26S Proteasome Structure and Function.
